DRAFT ATTACHMENT FOR STOVES.

SPEGIFKCAEION forming part of Letters Patent No. 640,484, dated January 2, 190 0.

[0 colt whom may concern:

Be it known that I, ANDERs G. NELSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Draft Attachments for Stoves,

of which the following is a specification.

This invention relates to improvements in draft attachments for stoves; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The object of my invention is to provide attachments for stoves which shall be of such construction and arrangement that they may be readily attached to almost any kind of a stove and when in position thereon will prevent the escape of all offensive odors arising from the cooking viands into the room and will conduct them to the stovepipe or flue.

In order to enable others skilled in the art to which my invention pertains to make and use the same, it will now proceed to describe it, referring to the accompanying drawings, in which Figure 1 is a front viewin elevation of the hood and a portion of the support therefor. Fig. 2 is a central vertical sectional view taken on line 2 2 of Fig. 1. Fig. 3 is a detail sectional view of a part of the rear portion of the hood, showing a means of securing said portion to the hood-support. Fig. at is a detached view in elevation of the supportingpiece. Fig. 5 is an edge view thereof, showing it attached to a part of the top of the stove. Fig. 6 is an enlarged View of one of the adjustable feet of the support, showing it detached therefrom. Fig. 7 is a side view thereof. Fig. 8 is a view in elevation of an adjustable holder, showing it connected to a portion of the supporting-piece. Fig. 9 is a plan view, partly in section, thereof. Fig. 10 is an end view of an attachment to he used 011 the holder. Fig. 11 is a front view thereof. Fig. 12 is a view in elevation of another attachment sometimes to be used in connection with the holder. Fig. 13 is a cross-sectional view thereof. Figs. 14, 15, and 16 are side views of different forms of stoves, showing the various ways of securing my attachment thereto; and 17 is a front view of a stove of the'form illustrated in Fig. 16, showing the means of connecting the attachment to its upper portion.

Similar letters refer to like parts throughout the different views of the drawings.

A represents the hood, which may be made of any suitable size, form, and material, but preferably of sheet metal and of the form illustrated in Figs. 1 and 2 of the drawingsthat is to say, with its base or lower portion rectangular in shape and its upper part inclined toward the stovepipe or line A, so as to form an apex a, which may be provided with rings a to receive cords or wires (not shown) to suspend the hood. Located in the rear portion of the hood are two pipes B and B, which communicate with each other and also with the stovepipo A, or the pipe B maybe made integral therewith. Each of the pipes B and B is provided with a damper b,of the ordinary or any preferred construction, which are, as

usual, pivotally secured in said pipes, so that they may be turned when it is desired to open or close the pipes. The rear lower portion of the hood is provided with a number of hooks or loops Z), riveted or otherwise secured thereto, to form sockets for the reception of the projections c on the upper end of the supporting-piece C, which is preferably of the form shown in Fig. 4 of the drawings and has vertically secured to its rear portion, yet a slight distance therefrom, two parallel bars 0' to act as braces for the supporting-piece, as well as a guide or support for the adjustable holder. Secured to the lower portion of the supportin g-piece C are two feet D, each of which con1 prises a piece d, having a hook d at its lower end and provided with a thumb-screw d to be used for securing the hook to the edge of the stove-top D, as shown in Fig. 5 of the drawings. Each of the pieces (Z is provided with a lug d on its front upper portion to fit in a slot (1 of a sliding piece (F, the lower portion (1" of which is extended at about a right angle therefrom, as shown in Figs. 5 and 6 of the drawings. The piece (Z is adj ustably held in position by means of a set-screw (1 which passes through the slot d and engages the piece (Z, as is clearly shown. The rear portion of each of the hooks cl is provided with an opening (Z to receive the set-screw (I when it is desired to clamp the supportingpiece to the stove-top from the rear. The adjustable holder E is made of two pieces e and 6, each having a longitudinal slot 6 through which passes a set-screw a which engages a block or head 6 interposed between the bars or rods and the supporting-piece O, as is shown in Fig. 9 of the drawings, and the two pieces 6 and e, which overlap each other, are held together by means of sleeves e which may be removed when it is desired to employ the other engaging devices, as will be presently explained. The ends of the pieces e e and e e are secured to blocks e on which are secured,by means of set-screws e or otherwise, arms 6 in which are located set-screws a, used for clamping a suitable portion of the stove.

In Figs. 10 and 11 of the drawings I have shown an engaging device F which I may use instead of the sleeves c and which device is provided with a hook f, to engage a suitable part of the stove. In Figs. 12 and l3is shown another engaging device G, through which the pieces'e and 6 pass and which has an arm g extending horizontally therefrom, on which is located a sleeve 9', having a set-screw g to clamp the piece g which is provided with a hook g", to the arm g.

In using the engaging devices shown in Figs. 10 to 13, inclusive, the rods or bars 6 are passed through the openings in said devices, when the hooks thereof willen gage a suitable portion of the stove, such as an upright part, with which some stoves are provided. 7

In using my draft attachment the feet D of the supporting-piece 0 maybe secured to the edge of the stove-top D, a part of which I have shown in Fig. 5 of the drawings, by means of the set-screws d and hooks d, said screws being interchangeble, so that they may be placed below the stove-top or on its outer surface when desired. The slide pieces d may be adjusted so as to rest on the upper surface of the top of the stove, as is apparent. When the stove is provided with an upwardlyextending portion, such as a warming oven or box or other upright portion, the adjustable holder E may be employed, with or withoutthe engaging devices shown in Figs. 10 to 13, inclusive, of the drawings. When said engaging devices are omitted, the arms e may be employed to clamp a proper portion of the stove.

From the foregoing it is evident that when the hood is thus supported above the stove and the damper b in the pipe B is turned so as to open saidpipe the fumes or odors from the cookin gviands will be drawntherethrough and escape through the stovepipe. It is further apparent that when the hood is support- ,60

ed above a gas-stove on which no stovepipe is employed the pipe B will act as a flue or stovepipe and, together with the pipe B, carry off the fumes and odors.

The pieces 6 and 6 may be provided with sleeves e to hold them together and to prevent them tilting on the pivot formed by the setscrew.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a hood having a pipe communicating at one of its ends with the stovepipe, and having its other end open, of a damper located in said pipe, a supporting-piece having means at its upper end to engage the hood and provided with two vertical parallel bars, the adjustable holder E, movably mounted on the supporting-piece and comprising the slotted pieces 6, and e, the head or block e, and set-screw e located in said slots and between the parallel bars, and means adj ustably mounted on the pieces 6, and e, to engage the upper portion of the stove, substantially as described.

2. The combination with a hood having a pipe communicating at one of its ends with the stovepipe, and having its other end open, of a damper located in said pipe, a supporting-piece having projections at its upper end to fit in sockets 011 the hood, the feet D, secured to the lower part of the supportingpiece and having the hooks 01, provided with the set-screws (Z and the slide-pieces 11*, provided with the arms d substantially as described.

3. The combination with a hood having a pipe communicating'at one of its ends with the stovepipe and having its other end open,

of a damper located in said pipe, a supporting-piece having means at its upper end to engage the hood and at its lower end to engage the stove-top, and provided with two vertical parallel bars, the adjustable holder E, movably mounted on the supporting-piece, and comprising the slotted pieces 6, and e, the head or block a, and set-screw e located in said slots and between the parallel bars, the pieces e and a, connected at their outer ends to the pieces 6, and e, and having means to engage the upward extension of the stove, substantially as described.
